Not all after market gauges wire right up to the newer trans. I've got a set of classic instruments gauges in my 1/2 ton with the electronic trans and ended up having to buy a box from them to convert the output from the trans to the correct number of pulses the gauges were expecting. I love the gauges and it was just another $75 bucks but wasn't expecting that extra cost.
Plus then I ended up with two sets of dips switches to deal with (one of the gauges, on of the converter box)
Make sure you let your gauge vendor know exactly what your hooking up to when you place your order. (as in what the trans originally came out of.)
